1: What is this graph known as?
A. A scatterplot
B. A box–whisker diagram
C. A histogram
D. An error bar chart
2: Based on the chart, what was the median mark (approximately)?
A. 72%
B. 58%
C. 77%
D. 65%
3: Based on the chart, what was the interquartile range of marks (approximately).

4: What does a histogram show? (Hint: Histograms are also known as frequency distributions.)
A. A histogram is a graph in which values of observations are plotted on the horizontal axis, and their density is plotted on the vertical axis.
B. A histogram is a graph in which levels of the independent variable are plotted on the horizontal axis, and the mean of observations is plotted on the vertical axis.
C. A histogram is a graph in which values of observations are plotted on the horizontal axis, and the frequency with which each value occurs in the data set is plotted on the vertical axis.
D. A histogram is a graph in which values of one variable are plotted against values of a different variable.
5: Imagine we took a group of smokers, recorded the number of cigarettes they smoked each day, whether they wanted to quit smoking or not, and then split them randomly into one of two 6-week interventions; ‘hypnosis’ or ‘nicotine patch’. After the 6 weeks, we again recorded how many cigarettes they smoked each day and subtracted this number from the number of cigarettes they each smoked pre-intervention, to produce an intervention success score for each participant. Out of the following options, which would be the best method of looking at which intervention was the most successful, taking into account whether the participant wanted to quit or not?
A. Clustered boxplot
B. Frequency polygon
C. Simple histogram
D. Population pyramid
6: What is the primary purpose of presenting educational data?
A. To manipulate data to fit predetermined conclusions

D. To hide important information from the audience
7: Which of the following is a commonly used graphical representation for presenting trends in educational data over time?
A. Pie chart
